摘要： The sealing of void spaces, e.g., as in geological formations and/or between metal shapes is accomplished with a liquid slurry of a particulate, water-soluble organic polymer in an organo solvent. The mixture of the polymer and solvent has a controlled set time to allow the emplacement of the slurry as a liquid. The slurry then sets to form a sealing cementitious material.

摘要： An aqueous solution of a water-soluble polymer which can be cross-linked in the presence of certain ions by adjusting the pH of the solution is disclosed. The aqueous solution contains a cross-linkable water-soluble organic polymer and at least two cross-linking agents (ions) for said polymer, each cross-linking agent (ion) being effective to cross-link the polymer at a different pH value. The pH of the initial solution is adjusted to a value between the two effective pH values where minimal (if any) cross-linking occurs. The pH can be adjusted up or down to within a range which is effective to cross-link the polymer.

摘要： THE SEALING OF VOID SPACES, E.G. AS IN GEOLIGICAL FORMATIONS AND/OR BETWEEN METAL SHAPES IS ACCOMPLISHED WITH A LIQUID SLURRY OF A PARTICULATE, WATER-SOLUBLE ORGANIC POLYMER IN AN ORGANO SOLVENT. THE MIXTURE OF THE POLYMER AND SOLVENT HAS A CONTROLLED SET TIME TO ALLOW THE EMPLACEMENT OF THE SLURRY AS A LIQUID. THE SLURRY THEN SETS TO FORM A SEALING CEMENTITIOUS MATERIAL.

摘要： A method is provided for plugging permeable materials, preferably permeable earthen materials. An aqueous solution having a neutral to basic pH and containing dispersed therein a water soluble organic polymer containing a plurality of carboxylic groups and an organic material having an acid reaction is acidized to form a precipitate in situ in the permeable material thus reducing the permeability of the material.
